MLK-17788 soc: imx: ipc: not abort when set wake error

When irq_set_irq_wake error, it means no irq wakeup capability,
showing the error msg is enough, no need to abort and cause
kernel stop.

For xen, currently we do not support suspend/resume, and
no wu interrupt controller support now, so need to remove
"return err" to avoid kernel stop.
